Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a paper cup portion for storing hot water at an upper portion, and an extraction portion for regular coffee or tea sandwiched between filter paper at the lower portion of the paper cup portion. And a paper cartridge comprising:

[Background Art] One of the conventional cartridges, for example, cassette coffee will be described.

The cassette coffee is generally formed of plastic material from the cup portion to the brewing portion, and the brewing portion at the lower portion of the molded product is also provided at the bottom of the cup portion with filter paper below, regular coffee in the middle and filter paper over the upper portion. The drip method is well known in which the hot water injected into the cup portion passes through the bottom extraction portion so that the coffee liquid is extracted.

"Problems to be solved by the invention"
When packaged together with a piece, it cannot be folded because the cup portion is integrally formed of a plastic material.

Therefore, since the packaging form when transporting the finished product of cassette coffee is inevitably large, the packaged product, the transportation cost is bulky, and when the cassette coffee is disposed of as one of the combustible materials in an incinerator after use, Hazardous gas is generated, and garbage disposal as one of the non-combustible substances causes pollution.

Further, since the plastic molded product is not easily damaged in the first use, even if the plastic molded product can be used repeatedly, it cannot be done due to the nature of the product, and it is disposable.

 In short, it wastes valuable resources.

Therefore, the cost of cassette coffee as a finished product is unavoidable.

Therefore, the entire cassette coffee is manufactured using paper and the paper cup portion is formed to be foldable, so that the entire thickness is formed thinner, thereby making it possible to reduce costs and eliminate pollution. It is one of the technical problems of the present invention.

“Means for Solving the Problems” The configuration of the present invention for solving the above technical problems is as follows.

A foldable quadrilateral paper cup portion and a through hole are formed substantially at the center of the bottom wall of the paper cup portion, and a number of slits are formed before and after the through hole in the bottom wall of the paper cup portion. Thereby, a support piece formed with the base on the concentric circle with the through hole as a fulcrum, an inverted dome-shaped lower filter paper and a flat upper filter paper are adhered to the bottom wall of the paper cup portion, and the lower filter paper and the upper filter paper are attached. It is an object of the present invention to provide a cartridge made of paper or the like, characterized by comprising an extraction part filled with powdered coffee or tea or the like.

[Operation] By pulling the seal or cut gather of the folded paper cup portion, it is easily opened right and left and a square box-shaped (mass-shaped) paper cup is formed.

Thereafter, the inverted dome-shaped filter portion of the mass-shaped paper cup is placed on a coffee cup, and hot water is poured into the mass-shaped paper cup so that the hot water passes through the coffee between the upper and lower filters, thereby extracting the coffee liquid. And fall into the coffee cup.

Also, since the filter is formed in an inverted dome shape, the hot water permeates all the way to the coffee and at the same time the coffee liquid is extracted.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a development view of the paper cartridge of the present invention, FIG. 2 is a vertical front view of the paper cartridge of the present invention, and FIG. 3 is a vertical front view showing a used state.

10 to form the paper cup part of the cassette coffee,
The paperboard 10 is cut into a square having a size of about 140 m / m on one side, which is a paperboard excellent in water resistance, heat resistance and flexibility.

Approximately 35 m / m from the front and rear ends and left and right ends of the square paperboard 10
Use appropriate tools to cut straight lines 101, 10
2,103,104 are formed, and then triangles (a) and (b) are formed by making diagonal creasing 109-112 in reinforcing members 105-108 formed at the four corners of the paperboard 10.

Next, on the left and right side walls 113 and 114 formed by the front and rear, left and right creasing 101 to 104, diagonal creasing 115 corresponding to the creasing 109, and diagonal creasing 1 also corresponding to the 110
16 and diagonal crevices 118 corresponding to the crevices 112 corresponding to the diagonal crevices 111 are sequentially inserted, as in the case of the diagonal crevices 117 corresponding to the triangular crevices 111.
(C) is formed.

A substantially square bottom wall 119 and front and rear walls 120 and 121 are formed at the center of the paperboard 10 by scoring 101 to 104 from the left and right front and rear ends.

Next, a through hole 122 is formed at the center of the bottom wall 119, and large and small creases 123 and 124 are formed concentrically with the through hole 122.
The slits 125, 125... Are cut in front and rear through a cutter as needed, so that a large number of support pieces 126 having support bones 128 for supporting the lower filter paper of the filter paper are formed.

In order to assemble the paperboard 10 formed as described above, first, the reinforcing member 105 is attached to the triangle (c) of the left and right side walls 113 and 114.
Front and left and right side walls 113, 114 and 120, 121 are bent 10
While standing up from 1 to 104, the reinforcing member
The inner surface of the triangle (a) of 105 to 108 is superposed and then the outer surface of the triangle (b) is superposed on the triangle (a) to form a square mass-shaped paper cup as shown in FIG. Become.

Next, reference numeral 20 denotes an extraction unit composed of a lower filter paper 201 and an upper filter paper 202. The lower filter paper 201 of the extraction unit 20 has a so-called inverted dome shape in which the lower part is a pot bottom.

In the inverted dome-shaped lower filter paper 201, the coffee liquid is concentrated at the center of the filter paper, and a small amount of coffee powder can be efficiently extracted.

Next, the upper peripheral edge 2011 of the lower filter paper 201 is
The lower filter paper 201 is heat-sealed (heat-fused) to the bottom wall and the outer periphery of the inverted dome shape of the lower filter paper 201 is heat-sealed to the inner periphery of the support piece 126, so that both are integrally formed.

 Thereafter, a predetermined amount of powdered coffee 203 is filled.

Next, the peripheral edge 2012 of the flat upper filter paper 202 is
Heat seal so that it overlaps the upper side of 1 and upper and lower filter paper 201,
The periphery of 202 is attached integrally.

After the paper cup unit 10 and the extraction unit 20 are formed as described above, when the triangular (d) portions of the left and right side walls 113 and 114 are pressed inward, they are folded along the creases 115 to 118 and at the same time. When the front and rear walls 120 and 121 are folded so as to face each other, the paper cup portion is flattened by fixing the edges of the paper cups with a seal.

At the time of use, the seal is peeled off to form front, rear, left and right side walls. When the side walls are further expanded, a square mass-shaped paper cup is formed.

In addition, a known cut gather can be used in place of the seal.

In this case, a tongue (bella) 129 is formed on one of the front and rear side walls of the square paperboard, and the tongue 129 and the front side wall 12 are formed.
A cut gather 130 is provided between 0 and a strong adhesive is applied in advance to the inside of the tongue piece 129, and after the paper cup unit 10 is folded, the release paper of the tongue piece 129 is peeled off and adhered. .

The above describes a product in which the cup portion 10 is formed from flat paperboard and then the extraction portion is formed.However, the present invention is not limited to this, and the extraction portion is incorporated into a pre-made product. Of course, it is possible.

[Effect of the Invention] Since the paper cassette coffee of the present invention has a paper cup portion for storing hot water and a paper extraction portion made of paper, the paper cup portion can be folded. When used, the paper cup portion can be expanded to form a square mass. It is very convenient because it can be formed in the paper cup part.

Since the cassette coffee is entirely made of paper, the production cost can be reduced and the cassette coffee can be stored in a carton without being bulky, so that the transportation cost and the like can be reduced.

In particular, before and after the formation of the paper cup portion, the length of the left and right side walls is about twice the length of the reinforcing member and the height is the same, so that even if they are overlapped at the border of the crease, they match, and a square square shape is formed. There is no protrusion from the periphery, and there is an advantage that the commercial value is not reduced.

When paper cassette coffee is used, when placed on the edge of the coffee cup, the square paper cup part has a large diameter at the tip of the corner and the diagonal corner of the coffee cup circle. This has the advantage that the mass is stabilized and the hot water flows down the bottom of the bottom, and at the same time, the coffee liquid being extracted can be seen from the gap between the square paper cups, and also has the effect of removing air during extraction.

Since the whole cassette coffee is paper, printing is possible, and the brand name, usage, and the like can be printed on the outside of the front, rear, left, and right side walls.

Also, the lower filter paper of the lower part of the cassette coffee extraction part has an inverted dome shape with a pot bottom, so that the hot water injected into the paper cup part passes through the coffee powder and is extracted at the center of the filter paper. At the same time, since hot water spreads over the entire surface of the coffee powder between the upper and lower filter papers, the coffee liquid can be sufficiently extracted even with a small amount of coffee powder without uneven extraction, and the extraction efficiency is further improved.

In the extraction unit, a support piece (including a supporting bone) formed on the bottom wall of the paper cup unit is formed integrally with the outer periphery of the filter paper by heat sealing. It also has the function of guiding the extract to the center.

Incidentally, the cartridge of the present invention is filled with coffee powder between the upper and lower filter papers as an example, but is not limited to this, as well as black tea between the upper and lower filter papers,
In addition, it can be used for oolong tea, jasmine tea and the like.

Further, the size of the paper cup can be appropriately changed according to the counterpart coffee cup.

Further, when the lower periphery of the lower filter paper and the inner periphery of the support piece are not integrally adhered to each other, both are somewhat unstable, but there is no particular problem in use.
